#### Cylinder Basic Scan - Wireframe Data Method

You can also use wireframe CAD data to generate a cylindrical scan.

To generate a cylinder:

1. Click near the desired wire on the cylinder. PC-DMIS highlights the selected wire.

2. Verify that the correct feature has been selected.

The BASICSCAN dialog box (Insert | Scan | Cylinder) displays the values of the selected cylinder's center point and diameter once the wire has been indicated.

If the underlying CAD element is not a cylinder or an arc, you may need to perform additional clicks to identify the feature. If PC-DMIS does not highlight the correct feature, try to click on at least two additional locations of the cylinder.

- CutVec: This vector is the axis of the cylinder and the plane in which the scanning is done.

- InitVec: This vector describes the direction in which the probe takes its first hit to start the scan. This vector is calculated according to the mode of data entry. This vector and the CutVec are normal to each other.
